Abstract

Background and Methods: Intracranial dural metastases are found in 9% of patients with advanced systemic cancer at autopsy. Detection of dural metastasis is as important as the systemic control of the cancer. We conducted a retrospective review of 25 cancer patients with dural metastasis from 2008 to 2010 and compared the cranial magnetic resonance imaging findings with clinical features.Results: Seventy-six percent of the parients were women; the mean age at diagnosis was 54 years. Breast (56%), prostate (12%) , lung (12%) and colon (8%) cancers were the most frequent tumors associated with dural metastasis. Unusual tumor types included chronic myelocytic leukemia (4%), carcinomas of bladder (4%), endometrium (4%). Dural metastasis were usually lineer, multiple, plaque-like and subdural lesions; coexisting with bone (84%) or skull metastasis (60%). On imaging, 44% patients had metastases of the brain parenchyma, 60% of lung and 64 % liver.Conclusions: Dural metastasis may arise from skull metastases or hematogeneous spread. Dural metastasis in the course of a spreading cancer is very important clinical problem for clinicians. Prompt diagnosis with neuroradiological methods is crucial. Large scale prospective studies are required to determine the true incidence and specific patterns of dural metastasis that could be specific to different cancer types.

Özet

Amaç ve Metodlar: İntrakraniyal dural metastazlar sistemik kanser nedeni ile otopsi serilerinde %9 oranında saptanmıştır. Dural metastazların araştırılması sistemik kanser kontrolünde önemlidir. Çalışmamızda 2008-2010 yılları arasında dural metastazı saptanmış 25 kanser hastasının kraniyal manyetik rezonans görüntüleme bulgularını klinik bulguları ile karşılaştırdık.Bulgular: Hastaların %76'sı kadın olup; tanı anında ortalama yaş 54 idi. Meme(%56), prostat(%12), akciğer(%12) ve kolon kanserleri en en sık dural metastaz görülen tümörlerdi.Daha az sıklıkla kronik miyelositik lösemi(%4), mesane kanseri(%4), endometrium malignitesi(%4) gibi tümöral olgularda da dural metastaz görüldü.Dural metastazlar genellikle lineer, multipl, plak görübnümünde subdural lezyonlar şeklinde görülmekteydi. Bu lezyonların birlikteliğinde %84 oranında kemik, %60 oranında kraniyal metastazlar saptandı. Görüntülemede, olguların %44'ünde beyin parankim metastazı %60 olguda akciğer,% 64 olguda karaciğer metastazları da eşlik etmekteydi.Sonuç: Dural metastazlar genellikle kraniyal kemik metastazlarından veya hemotojen yayılım sonucu oluşabilir.Dural metastazlar klinisyenler açısından kanser yayılımını belirlemeleri nedeniyle önemli bir klinik problemdir.Nöroradyolojik tanı yöntemleriyle tanımlanmaları klinik öneme sahiptir.Dural metastazların gerçek insidanslarının ve değişik kanser türlerinde spesifik olabilecek radyolojik görünüm şeklinin belirlenmesi için geniş serilerle prospektif çalışmaların yapılması gereklidir.
